Question 3: How to start the container and how to configure the parameters
The parameter configuration of starting the container is a relatively complicated process, which needs to be configured differently according to our needs. I will give an example of how to operate mysql startup configuration?
Question 2: Daily operation commands
1. Load the image
docker load -i xxx.tar
2. Save the image to tar locally
docker save -o File name to be saved Image ID to be saved
3. Copy files to the container
docker cp ./xx.tar ID:/root
4. Copy from the container to the host host
docker cp ID:/xxx.tar ./
Question 1: Daily update and upgrade! ! ! !
Solution 1: Directly create the mirror image in the company, and then replace the entire mirror image;
Solution 2: Change the program in the mirror directly. The disadvantage is that the mirror package will be large after the replacement is completed; it can be optimized later...
